Around this lab: Waseca County, MN

• Private wells: about 5,909 people, 31% of Waseca County’s 18,989 residents (USGS, 2015); rank 52 of 87 counties in Minnesota by people on wells.
• At house sale: Waseca County has a septic system rule (Waseca County SSTS ordinance (section not cited)). What it requires

• EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 1,434 private-well users (95% range 1,130 to 1,792; 2010 base), rank 18 of 87 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 70% of 7,922 housing units were built before 1980, above the state share of 52%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
• PFAS in public water nearby (public supply, not your well): 1 public system serving this county reported EPA UCMR 5 results; 0 had a PFOA or PFOS sample at or above 4.0 ng/L.

Before you send a sample

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Minnesota certification program.
